On July 30, 2025, an 8.7-magnitude underwater earthquake hit off the coast of Russia's Kamchatka Peninsula. The quake happened at 8:25 a.m. local time. It was first recorded as an 8.0 quake, but the US Geological Survey later changed it to an 8.8 quake.
This week, a high-magnitude quake sent tsunami alerts all over the Pacific. Russia, Japan, Alaska, Hawaii, Australia, New Zealand, and some parts of North and Central America started to get hit by waves that were moving along the coasts. Japan saw waves as high as 60 cm, and some parts of Russia were flooded up to 4 meters deep.
People in Russia's Severo-Kurilsk were forced to leave their homes because of flooding, and the local government announced a state of emergency. There were reports of minor damage to infrastructure, like a kindergarten being broken into, and power outages, but no major injuries have been confirmed.
Honolulu's emergency sirens went off, telling everyone to leave because of "destructive tsunami waves." People who live on the US West Coast, from California to Alaska, were warned about tsunamis. People who live on the coasts of Mexico, Canada, Ecuador, the Galápagos Islands, and New Zealand were also warned.
Will India Be Impacted?
The Indian National Centre for Ocean Information Services (INCOIS) says that there is no danger of a tsunami to India or the Indian Ocean region, even though the earthquake was very strong and there were global alerts. It was too far north and in the northern Pacific area for the earthquakes to have sent waves all the way to India.
The Indian government is keeping a close eye on things. At the same time, the Indian Consulate in San Francisco warned Indian citizens to be careful in the affected areas, especially along the US West Coast and in Hawaii, because of the risk of sea swells. People were told to pay attention to local warnings, stay away from beaches, and charge their phones and other devices in case they needed to.
What took place and what will happen next?
The centre was about 120–125 km east-southeast of Petropavlovsk-Kamchatsky, and it was only 19–20 km deep, which makes it more likely that a tsunami will happen.
After the main shock, there were several strong aftershocks, some reaching as high as magnitude 6.9. This made people worry that the seismic activity might not stop.
Tsunami waves can come in waves that last for hours or even days, and each wave can get bigger than the last.
